REEEIGERATOEt-BODY FOR VEHICLES.

Application filed october 11 legheny ll of Pennsylvania, have inven or discovered new, useful, and improved liefrigerator-Bodies for Vehicles, of which the following is a specification.

v invc. tion consists in certain new and us cl improvements in refrigerator bodies for vehicles intended for the Wholesale deimery of ice crcsmend other frozen products. i

in the case of vehicles oil this character, the load or burden usually consists of the :5" men products packed in and other siners together with a supply oi? refrigi such broken ice and salt for prethe products on route, for packing the products es they are delivered, and for citing such products as may have been over in the customers possession from previous delivery. I

impor not that the vehicle may be a minimum oi handlingthe rest of the load.

.lt is also important that the product be kept .i] the proper temperature while on route. it n is t'urt ier important to keep the weight or the body down much as possible to reduce t e dead load.

For the accomplishment of these, and other, advantageous results, I provide a vehicle body having a storage compartment for holding and refrigerating the products, whose roof is formed of a pan or shallow container adapted to be filled with broken ice and salt and having walls formed of vertically disposed tanks, adapted to be iilled with brolren ice and also to receive the drip from the aforementioned pan, said tanks being provided at their lower ends with drainage means. A suitable closure is provided for the top of the ice pan, which inclosure is, at least in part. removable to permit loading; 0:" id pan. Doors are provided in the side walls oi? said body for access to said compartment.

The body is also provided, preferably at the rear of the product storage compartment above referred to, with an ice storage conipartment to which loadi sccess is had through the root or top oi the body, and

from which the broken ice is removed at the rear of the vehicle body by means of a rearwardly extenol downwardly inclined chute .vhose f scharg'e end is preferably incioscd by no" nd. improved end gate struc- LL59.

; it also provide, preferably in the extreme rear of the body, a salt compartment into which the salt is loaded at the-top and which is provided with an internal, inclined balllc adopted-to d rect the in a pile on the bottom of the compatment within easy reach of an access hole in the back end of the vehicle through which a scoop may be inserted.

also provide an open top apartment, preferably above the ar portion of the ice compo .inent, to receive empty containers collect from customers, or, when necessary, an. en ra supply of ice.

(Ether novel features of construction and ar gemcnt of parts will appear from the iollowin description.

3 e following is a detailed description of the drawings, reference being first had to Figs. .1 to 5, inclusive.

The body is of the inclosed type and coin prises, generally, a product storage compartment A; an ice storage compartment l5, preferably next in the rear, and a sit storage compartment preierably in the rear of the ice compartment B and at the rear of the body.' I also prefer to provide an open top compartment D, preferably in front of the upper portion of the salt compartment C and extending down into the ice storage side and front edges flanged up at 2 against the front and side walls of the vehicle. T he floor 3 of the vehicle extends: under the 7 whole of the compartment'ir but under the compartments B and C the floor is interrupted alongthe horizontal center of the body to provide space for the rearwardly inclined chuted which, extends from the front of the compartment B to the rear of the body. The metal floor covering 1 iscontinned to t-he rear of the vehicle to form the floor of the chute l, andthe chute is provided with sides 5 which extend up to and support the chute from the floor beams. The floor er the compartment A is preferably slightly inclined towardthe'rear so as to drain into the chute 4.

The front and rear walls of the comparte ment A are formed by vertically disposed tanks E, preferably made of heavy, galvanized sheet metah The backs 6' of said tanks are flat and extend up to fitthe double pitch ofthe roof; Thefronts"? of said tanks are formed of vertically corrugated jor fluted metal to provide an increased radiating surface. The ends 8 of the tanksare flat and may be formed by hanging the front and back sheets and: riveting or soldering the flanges together. The front tank rests against the front wall of the vehicle body, while the rear tank. separates the compartments A and B. In the rear of the upper back wall of the rear tank E, a strut or partial partition 9 connects the body sides having its top edge. double pitched to support the roof doors. Vertical cleats 10 secured to the body sides may also be provided;

to'h'old the tanksi'n proper'position and alinement. f

The interiors of the tanks are braced by vertically disposed bars 11, andinthe bottoms of the tanks 1 fix the inverted trough shaped metal members 12 having parallel sides, and whichsupport'theice in'the tanks] but permit themeltage to run. downalong the interiorsof the corrugations in the front the tanks.

' compartment A.

walls." The bottoms of the tanks are stepped in the shallow metal troughs or boxes 13, closed at their ends, and which rest on the floor of the 'compartment and thus support Said boxes. are provided with drain pipes 1a which depend through holes.

' in the body floor and are threaded to receive the traps 1 1* which may be removed to permit the tanks to beflushed'out with a hose to carry off sand and other foreign material deposited from the broken ice and salt.

F represents a panor shallow container horizontally disposed to form the top of the Said container is prefer ably made of heavy'galvanized iron. It is provided with shallow sides 15 having outwardly turnedtop tlanges'16 which rest' upon the top edges of the side walls of the body and are secured in place by nails or screws. The pan is also provided with angle joist or braces l'Zto support thebottom 18 of thepan, said joist having bent ends which are securedby bolts or screws to the body sides. ilhepan spans the spacebe tween thetwo tanks E and atv its ends the bottom 18 is flanged downwardlv within said tanks and riveted to their front walls 7 boltedtofthefront'wall'of the adjacent tank 7 E while its vertical leg is .boltedto one of the 'joist'17.

Access is gained to the compartment A by means; of doors 22 in the side walls of the body at the lower centers of the compartments. V r

' The rear wall of the tank E which forms the partition between the compartments A and B is preferably provided at its bottom with a sliding door 23 so that in case the 7 ice stored in the compartment 13 is ex hausted, an auxiliary supply may be taken from the interior'of the tank through said door. 3

The compartment D which is formed from space borrowed from the upper rear portion of the compartment B is formedby' the partition'QeL, which forms the front wall of the salt compartment C, the horizontal floor 25 which is'supported by the side walls of the body, and the front partition 26. extending down to said. floor 25. The top of the partition 26, as is alsothe frontwall of the body, is given the proper pitch to carry the roof structure.

The compartments A and B are provided with permanent root portions 27 at the sides and pairs of top doors 28 which meet and lap in the center to form the ridge and are ippc-rted by the front wall of the body, the partition 9 and the partition 26. If desired the compartments C and D may be provided with similar roof structures but usually these are omitted.

The salt compartment C is provided with a floor 29 which bridges the chute 4, and above said floor an inclined baiiie 30 extending from one side of the compartment, preferably the right side, toward the other side so that the salt will keep sliding down said battle and pile up on the floor below the lower end of the battle. Toward the right side of the body and below the battle 30, the rear wall of the body is providedwith an aperture 31 through which a scoop may be inserted to take out salt. Thus the aperture may be left open for easy access without possibility of spilling out the salt.

32 represents the end gate which closes the rear or discharge end oi the chute 4. The bottom of said gate is hinged to the bo tom edge of said chute and 38 are supplemental side plates attached to the ends of said gate and moving against the sides of said chute so that when the gate is open, a box with closed ends is formed from which the ice sliding down the chute may be shoveled as needed. 34: is an iron whose ends are horizontal and attached to the bottom of the vehicle body while its intermediate portion forms a rectangular saddle with its bottom bearing against and secured to the under side of the chute to support the same, while its vertical legs extend up outside of the side plates 33 of the end gate 82 forming slots for said side plates to move in. Said side plates are provided with projections which are adapted to engage said iron and thus limit the opening of said end gate. 36 is a fastening to hold the end gate in its closed position.

in Figs. 6 and 7 I show my invention developed in connection with a wagon or animaldrawn truck in which case the drivers *ab usually extends back into space borrowed from the compartment A and said compartmentis extended under the drivers seat, as at 37. in this case the front ice tank E does not extend down to the floor but is supported by cleats 38 attached to the body walls so as to give access to the space 37 under the drivers seat.

In the case of animal-drawn vehicles, to save weight, T use a padded canvas cover instead of the wooden doored root shown in connection with the motor truck body.

Thus said cover is made in two parts; a front part G which forms the root of the compartment A, and the rear part H which forms the roof of compartment .B. The cover G is permanently secured at its front to the front wall of the body and is detachably secured in position over the compartment A as by lashings 39 so that the cover can be rolled orfolded forwardly for loading ice into the tanks E and ice and salt into the pan F. permanently attachedto the top of the partition 26 and detachably held in place as by lashings 39 so that said cover may be rolled or folded back to permit ice to be loaded into the compartment B.

The covers are centrally supported by the horizontal ridge pole or beam 40 which runs from the front wall of the body across the partition 9 to the partition 26. v

At thestart of a trip the tanks E are loaded with cracked ice and the pan h with ice and salt. Ice is also loaded into the compartment 13, and if required also into,

not already packed in a tub, he proceeds to pack the container in a tub with ice and salt taken from the rear of the body. The container is already. in a tub but owing to meltage requires repacking, the driver drains oil the water from the tub and repacks the later with ice and salt.

The ordinary practice in ice cream delivery is to use an open top wagon and piling the broken ice about the tubs inwhich the containers are packed. This entails a great wastage of ice and it is hard to deliver the products in good condition. it is also inconvenient and requires much lifting and rehandling of the containers and tubs.

My improved vehicle body is very con venient to work with as the supplies of ice and salt are readily gotten at and handled, and the product can be readily and quickly removed when needed. The body may also.

be loaded with product and refrigerants very quickly. A minimum amount of refrigerants are required to keep the product in a well frozen condition on route, and such refrigerants are so disposed as to take up but little valuable space in the body. The body is therefore much lighter than other vehicle bodies in which an attempt is made to refrigerate the product during its transportation.

In my improved body the rear ice tank E not only refrigerates the contents of the compartment A, but it also retards the melting of the supply of ice carried in the comoartment B.

I recommend that, as the filled containers Similarly the cover H is" are received from't-he compartment A, empty containers with their lids in'place besubstituted in said compartment, thus occupying space which would otherwise be occupled by warm from outside.

lNhile my vehicle body has been especially designed for the-transportation of frozen food products, such as ice cream, 1t 18 quite evident that it may be advantageously used for transporting any character of substances, materials or articles which require a low temperature for preservation.

Although, for the salre of clearness, I have minutely described the embodiment of the principles of my invention, as the same are illustrated in the accompanying drawings, 1 do not wish to limit myself thereby, but claim broadly 1. In a vehiclelbody for the transporta tion of frozen products, a product compartment having walls comprised of vertically disposed ice tanks, means spaced above the bottom of said tanks for the support of their solid contents, trough members in which said tanksare stepped, and drainage means for said trough members. 7
